FRONT FEED. PAPER GAUGE Filed March 10, 1950 L 3 W 29 Z9 /N 5 N TOR 7-7:4 25 2/ .WAL TER A. ANDERSON D W8 ATTORNEY Patented Jan. 27, 1953 FRONTFEED PAPER, GAUGE Walter A. Anderson, Bridgeport, Conn, assignor toUnderwood Corporation, New York, N. Y., a

corporation of Delaware Application March 10, 1950, Serial No..1-48,7984 Claims. (Cl. 197- 14 This invention relates to a tabulating carriagefor an accountingmachine and more particularly to adjustable stops forthe rear edges of sheets inserted from the front of the carriage.

It is desirable to provide accounting machine carriages adap-tedforfront feeding of work sheets with adjustable stops to facilitate rapidand accurate insertion of such sheets. Such stops should be light,simple and inexpensive but should be adjustable both as to lateralposition and as to stopping depth to accommodate sheets in differentlateral positions and to arrest the work sheet at the various printinglines, Such stops should also be removable. It is accordingly an objectof the present invention to provide a stop for the rear edge of a frontinserted work sheet which stop is composed of a few simple lightelements and yet is readily adjustable laterally of the carriage.

Another object of this invention is to provide a readily removable paperstop to permit the machine to be used for long front fed sheets or tovary the number of sheets which are to be used;

Still another object is to provide a paper stop which is readilyadjustable to arrest a front fed sheet at any desired printing line.

Other incidental objects of the invention will be set out in theaccompanying specification and drawings.

In the drawings:

Figure 1 is a side view, partly in section, of the accounting machinecarriage showing one of the paper stops,

Figure 2 is a front view of the stop of Figure 1,

Figure 3 is a sectional view of the stop taken along the line 3-3 ofFigure 2, and

Figure 4 is a sectional view of the stop taken along the line 4-4 ofFigure 2.

A preferred embodiment of the paper stops is described herein as appliedto the carriage of a conventional Sundstrand accounting machine of thetype described in U. S. Patent No. 2,088,982, issued to Oscar J.Sundstrand, August 3, 1937. This accounting machine includes generally abase section carrying the keyboard, the register, and the type bars anda carriage movable laterally on the main section to position differentcolumns of'work sheets carried thereon at the printing zone of the typebars.

Referring to Figure 1, the carriage, designated generally at It, islaterally movable on a rail ll secured to the main machine frame. Aplaten I2 is rotatably carried between the side Walls of the carriage topresent work sheets passed around it to the usual type bars 13. Theplaten i2 is 2 provided with the usual sets of feed rolls I4 to pressthe paper against platen l2, only one of such feed rolls being shownherein. The carriage Hlsupports two paper tables l5 and I6,,the fronttable l5 serving to direct rear inserted sheets betweenthe platen l2 andfeed rolls l4 and the rear table 16 being for front inserted sheets.

A front inserted Work sheet F is directed by a chute l'l to pass betweenplaten l2 and 'a deflector plate H3. The sheet F is deflected by platel8 into a throat formed bythe lower curved edge of the rear paper table16 and the curved forward projections ofarms 19 which support feed rollsl4. A plate 20 secured parallel to the paper'table '16 forms with tableIS a chute to guide sheet F into the rear edge stops which can be set todetermine the limit to which sheet F may be inserted.

A square bar 2| to carry the rear edge stops is secured between the endsof carriage Ill and passes above and to the rear of the paper table l6.Each rear edge stop, 'see also Figures 2, '3 and 4, is formed of a strip22 bent into a U shape. Two cars 23 are bent rearwardly from strip 22and are perforated'with asquare hole of substantially the same size asbar 2|. Each "ear '23 is also slotted at 24, from the bottom into theperforatedhole to permit removal of the stop 22 from bar 21.

For such removal, bar 2! is, at two places 25, adjacent to one end, seeFigure 4, notched down to approximately the size of slots 24, thedistance between the notches 25 corresponding to that between ears 23.Each stop is then removable by sliding it to register with notches 25 atwhich point it may be easily lifted from the bar. A leaf spring 26secured to the rear of stop 22 presses against the front face of bar 2|to frictionally retain stop 22 against lateral movement.

The front leg of strip 22 is slotted at 21 to permit adjustment of apaper engaging stop slide 28 slidable between the legs of strip 22. Stopslide 28 is formed with two rearwardly extending perforated cars 29. Abowed flat spring 30 passes through the perforations in ears 29 andpresses against the rear side of strip 22 to frictionally retain slide28 in its adjusted position. Slide 28 is also bent to provide two ears3| and 32. The upper car 32 is wider than slot 21 and is provided withnotches 33 into which the two sides of slot 2'! fit. This engagementserves to retain the two legs of strip 22 at the proper separation andthe protruding end of ear 32 may be grasped to move slide 28 on strip22. The lower ear 3| extends into slot 21 to close the gap between thefront and rear legs of strip 22 and thus acts as a paper stop for sheetF.

In use, a front sheet F is inserted in the chute l1 and moveddownwardly. The bottom edge of sheet F first engages deflector plate I 8and passes into the throat formed by table It and arms l9 and plate 20,after which it passes between the legs of strip 22 until arrested by ear3! of slide 28.

It is then evident that stop 22 is laterally adjustable on bar 2! to anycolumnar position and may be easily removed therefrom thus permittinguse of as many front fed sheets as desired and in any selected columnarpositions. The depth of insertion of any sheet maybe readily determinedby proper positioning of the sliding stop 28 on each stop 22.

Many modifications of the structure above described are possible withoutdeparting from the spirit of the invention and the scope of theinvention is to be limited only by the following claims.

What is claimed is:

1. A record making machine including a carriage, a platen in saidcarriage and members on said carriage to direct a, front inserted worksheet about said platen, a flat sided bar on said carriage, and a paperstop mounted on said bar to receive .and arrest the leading edge of saidsheet, said paper stop comprising a U-shaped strip, projections near oneend of said strip to engage said bar and retain said stop in apredetermined orientation, means on said strip to frictionally engagesaid bar and restrain said strip against lateral movement on said bar, astop member positioned on one of the legs of said strip and obstructingthe space between said legs to engage on said bar to receive and arrestthe leading edge of said work sheet, said paper stop comprising aU-shaped strip, means on said strip to engage said bar to retain saidstop in a predetermined orientation, spring means on said strip tofrictionally engage said bar to restrain said stop from lateralmovement, a slot in one leg of said U-shaped strip, a stop memberslidable on the other leg of said strip and frictionally held in anadjusted position thereon, a stop lug on said stop member, and a.notched lug on said stop member to engage the edges of said slot insaid; strip and maintain a predetermined distance between the legs ofsaid strip.

3. A paper stop for a record making machine including a movablecarriage, said stop comprising a folded strip having two substantiallyparallel, spaced legs, a stop member positionable on one of said legs,frictional means to hold said stop member in any adjusted position,means on said stop member to engage the other of said legs and retain itat a fixed distance from said first leg, and means for mounting saidfolded strip on said carriage.

4. A paper stop gage for a record making machine including a carriageand means on said carriage to guide a record sheet in a predeterminedpath, said paper stop gage comprising a strip folded to provide twosubstantially parallel spaced legs, a stop member slidable on one ofsaid legs, means to frictionally retain said stop member in any adjustedposition on said leg, means on said stop member to engage said other legand retain it at a fixed distance from said first leg, means to mountsaid folded strip on said carriage with the open end of said strip inposition to receive the record sheet therebetween and said strip free tomove laterally of said carriage, impositive means to hold said stripagainst lateral movement and a paper engaging lug on said stop member.
